Electrical equipment should not be operated in the vicinity of gases, e.g. flammable gas used
in anaesthesia or similar gases. The user is responsible for maintaining this requirement and for
compliance with IEC 60601-1-2 standard.
Equipotential bonding should be carried out for the uni-cart, pro-cart, classic-cart, compact-cart
or endo-cart carrier system with an isolating transformer. vexio-cart offers an optional POAG set
without isolating transformer. The equipotential bonding cable should be first connected to the
base of the uni-cart, vexio-cart, pro-cart, classic-cart, compact-cart or endo-cart carrier system
and then be connected to the equipotential bonding plug in the room. Next, connect the POAG
supply cables to the POAG pins of the multiple sockets and the appliance.
The uni-cart, vexio-cart, pro-cart, duo-cart, compact-cart, classic-cart or endo-cart carrier system
is intended to provide a practical and mobile workstation for medical electrical equipment. Total
earth leakage currents must not exceed a maximum value of 0.5 mA so that the entire medical
electrical system can be compliant with IEC 60601-1. If the sum of the ground leakage currents
would exceed the tolerance range, the system must be supplied through a safety transformer.
If an isolating transformer is not mounted, the multiple socket strip / auxiliary socket strip system
of the uni-cart, pro-cart, duo-cart, compact-cart, classic-cart or endo-cart carrier system must not
be used to connect up equipment that is not in conformity with requirements for earth leakage
currents under IEC 60601-1.
If an isolating transformer is mounted, the total power uptake of all the connected units must
remain within the rated value for the isolating transformer.
The following descriptions are only applicable for the carrier systems in which the item "isolating
transformer with insulating monitor" is installed.
At the devices with integrated-earth-leakage guard the evaluation unit is in the transformer case,
the separate control panel is placed in one of the shelves. Both components are connected
with an interface cord, which lays in one of the profiles.
